On S-asymptotically omega-periodic functions and applications
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
Let (X, parallel to . parallel to) be a Banach space and omega is an element of R. A bounded function u is an element of C([0, infinity); X) is called S-asymptotically omega-periodic if lim(t ->infinity)[u(t + omega) - ...
Dynamics of a chemostat with periodic nutrient supply and delay in the growth
(IOP Publishing, 2020)
This paper introduces a new consideration in the well known chemostat model of a one-species with a periodic input of single nutrient with period omega, which is described by a system of differential delay equations. The ...
Poincare's problem in the class of almost periodic type functions
(Belgian Mathematical Soc Triomphe, 2015)
We consider the Poincare's classical problem of approximation for second order linear
differential equations in the class of almost periodic type functions. We obtain an explicit form
for solutions of these equations by ...
The effects of pinning on critical currents of superconducting films
(2013-06-01)
Using molecular dynamics simulations, we analyze the effects of artificial periodic arrays of pinning sites on the critical current of superconducting thin films as a function of vortex density. We analyze two types of ...

Weighted pseudo almost periodic functions, convolutions and abstract integral equations
(Elsevier, 2016)
This paper deals with a systematic study of the convolution operator Kf = f (*) k defined on weighted pseudo almost periodic functions space PAP(X, rho) and with k is an element of L-1(R). Upon making several different ...
WEED INTERFERENCE PERIODS IN PRE-SPROUTED SUGARCANE SEEDLINGS
(Univ Federal Vicosa, 2019-01-01)
The aim of this research was to determine weed interference periods in sugarcane cultivated under the system of pre-sprouted seedlings, taking into account the impact on the final plant stand, and bud yield and stalk yield. ...
Sufficient conditions for the existence of periodic solutions of the extended Duffing–Van der Pol oscillator
(2016-08-02)
In this paper, some aspects on the periodic solutions of the extended Duffing–Van der Pol oscillator are discussed. Doing different rescaling of the variables and parameters of the system associated with the extended ...
